Linear 0-291312RU PIP12VDCRU 12 VDC 2 Amp Plug-In Power Supply
The PIP12VDCRU is a plug-in regulated DC power supply used to power compatible Linear / IEI low-voltage access control components. Unlike a basic transformer, it supplies regulated 12 VDC output and includes protection features intended for access-control electronics. It is often selected when a keypad, reader, controller accessory, or interface module needs a dependable 12 volt DC source.
Power supply selection matters because access devices can look similar while requiring different voltage, current capacity, or AC versus DC input. Using the wrong supply may cause intermittent operation, keypad resets, reader dropouts, damaged electronics, or nuisance access-control failures. Always compare the device label and installation instructions to the 12 VDC, 2 amp rating before replacing an existing supply.
Compatible With
Used with compatible Linear / IEI access control devices and other low-voltage equipment that specifically requires regulated 12 VDC power within the 2 amp output rating.
- Linear / IEI access control keypads requiring 12 VDC input within the rated current draw
- Compatible Linear card reader and reader-interface applications where a separate 12 VDC supply is specified
- Compatible eMerge, Max, Hub, or IEI accessory installations when the device documentation calls for 12 VDC external power
- Low-voltage access-control accessories such as interface boards, small modules, and powered peripherals within the supply rating
- Not a replacement for 12 VAC, 16.5 VAC, 18 VAC, 24 VAC, or battery-charging transformers unless the equipment specifically accepts 12 VDC

Technician Note
If a keypad or reader repeatedly resets, drops offline, or works only intermittently, check voltage at the device under load. Long cable runs and undersized wire can cause voltage drop even with a good power supply.
Before Ordering Checklist
- Confirm the device requires 12 VDC, not AC voltage.
- Add up the current draw of all connected devices and keep it within the 2 amp rating.
- Check polarity before connecting DC-powered equipment.
- Inspect the outlet and retaining screw location if wall mounting is required.
- Verify whether the existing system uses a separate battery backup or controller power supply.
Important Ordering Warnings
Do not substitute this 12 VDC supply for an AC transformer or gate battery charger. AC and DC supplies are not interchangeable unless the connected device specifically allows it.
Professional Advisory
Access-control power issues can affect locks, strikes, readers, and gate relays. A qualified technician should inspect systems with repeated fuse trips, overheating, damaged cable, or door/gate security concerns.
Product Q&A
What output does the PIP12VDCRU provide?
It provides regulated 12 VDC output up to 2 amps, or 24 watts maximum.
Is this the same as a transformer?
It acts as a plug-in power supply for 12 VDC devices, but it is not the same as an AC transformer used by some gate operators.
Can it power more than one device?
Only if the total current draw stays within the rated output and the wiring is sized correctly.
What does the LED indicate?
The red LED on listed versions gives a quick indication that the supply is powered.
Why does polarity matter?
DC-powered keypads, readers, and boards can fail or act unpredictably if positive and negative leads are reversed.
